Q_1_12 — Conformal Cyclic Cosmology: Penrose's Vision of Eternal Recurrence

Conformal Cyclic Cosmology (CCC), proposed by Roger Penrose in 2005, envisions the universe as an infinite sequence of "aeons" — each beginning with a Big Bang-like event and ending in an infinitely expanded, cold state

Q_4_06 — Baryon Asymmetry and Matter-Antimatter

One of the deepest unsolved problems in physics is the baryon asymmetry of the universe — the observed predominance of matter over antimatter. For every ~10⁹ photons in the cosmic microwave background, there is approxima

Q_2_11 — Stellar Populations, Metallicity, and Generations

Stars preserve the chemical fingerprint of the gas from which they formed, making them archaeological records of the universe's chemical history. Walter Baade (1944) recognized two distinct stellar populations: Populatio

Q_2_04 — Stellar Evolution: The Life Cycle of Stars

Stars are born in collapsing molecular clouds, live by nuclear fusion for millions to trillions of years, and die in ways determined almost entirely by their initial mass. Low-mass stars (< 8 M☉) shed their outer layers
